Welcome to Healing Well! I'm sorry to hear you're suffering so much with GERD. You're definitely in the right place. I am sure that you're following GERD lifestyle suggestions: http://www.mayoclinic.com/health/gerd/DS00967/DSECTION=lifestyle-and-home-remedies
Since you're finding that medication is not controlling your symptoms, and if they are severe, it sounds like you might want to consider a surgical solution.
Many here have had Nissen fundoplication surgery with very good success. I was one of them...my reflux wasn't horrible, but it was bad enough to make my lungs very unhealthy. I had surgery in February 2009, and it gave me healthy lungs again.
I'm sure others will be by to say hi and share their own experience and support.
